I do not have any external checks that run once per minute nor have I created a consul health check for vault so I suspect this comes from an automatic vault/consul health check. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the cryptographic algorithms they will use, and agree on session keys. For more information, see What are the current cipher suites supported by Azure Front Door?. It could be something like a network firewall preventing the connection, or it could be a configuration on an edge device on the server-side network. Most browsers will cache certificates so that upon return to a website it makes the handshake go faster. Its also worth noting that, sometimes, these issues will materialize into a different error on the client-side as opposed to the SSL/TLS handshake failed message. 20150929 03:00:43 Restart pause 2 second (s) Server OpenVPN Open Access Server (10 licenses) Server Error: 015-09-29 03:06:28-0700 [-] OVPN 1 OUT: 'Tue Sep 29 10:06:28 2015 Authenticate/Decrypt packet error: packet HMAC .
